Abstract: In accordance with some embodiments, wireless communication for transmission of a beam failure recovery (BFR) MAC-CE is disclosed. A method performed on a user equipment (UE) includes detecting a beam failure of at least one beam of a beam group. The method further comprises triggering a BFR in response to the detection of the beam failure of the at least one beam of the beam group. In addition, the method includes generating a BFR medium access control-control element (MAC-CE) that includes BFR information associated with the beam group. Further, the method comprises transmitting the BFR MAC-CE that includes the BFR information associated with the beam group using a transmission resource.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives signaling configuring the UE with a control resource set (CORESET) activated with two transmission configuration indicator (TCI) states. The UE further receives a downlink control information (DCI) triggering transmission of aperiodic channel state information (CSI) reference signals (RSs) on aperiodic CSI-RS resources. The UE applies a quasi-colocation (QCL) assumption of at least one of the two TCI states for processing the aperiodic CSI-RSs, when a scheduling time offset is less than a threshold value and depending on whether same or different aperiodic CSI-RS resources are received from two transmission reception points (TRPs) associated.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of a set of linked physical downlink control channel (PDCCH) candidates if the UE selects to monitor a subset of the linked PDCCH candidates. In one aspect, the UE may monitor the subset of the linked PDCCH candidates, and the UE and the component of the BS may select a reference PDCCH candidate from which to define scheduling information in accordance with the UE monitoring the subset of the linked PDCCH candidates. In some examples, the UE and the component of the BS may select the reference PDCCH candidate in accordance with one or more mutually understood rules or procedures such that the UE and the component of the BS may select a same reference PDCCH candidate.

Abstract: In accordance with some aspects, a method of wireless communication performed by a user equipment (UE) is disclosed. The method includes monitoring for beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell, the group of beams associated with a group beam identifier; measuring, based on the monitoring for the BFD RSs, a reference signal received power (RSRP) of one or more of the BFD RSs; and triggering, based on the RSRP being below a threshold, a beam failure recovery (BFR) process for the group of beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink control message scheduling multiple downlink transmission repetitions of multiple transport blocks (TBs), the downlink control message indicating a specified transmission configuration indicator (TCI) state for receiving the multiple downlink transmission repetitions according to the scheduling, the multiple downlink transmission repetitions including a first set of downlink transmission repetitions and a second set of downlink transmission repetitions. The UE may be configured to receive, via a default TCI state different from the specified TCI state, a first subset of downlink transmission repetitions from the first set of downlink transmission repetitions, the second set of downlink transmission repetitions, or both, based on a first time interval between a receipt of the downlink control message and a receipt of at least one downlink transmission repetition failing to satisfy a time duration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a scheduling configuration for scheduling communications on a first component carrier. The scheduling configuration may indicate at least a first downlink control channel candidate on a second component carrier that is linked for control message repetition to a second downlink control channel candidate on one of the first component carrier or a third component carrier. The UE may then receive, from the base station and based on the scheduling configuration, at least one repetition of a control message in the first downlink control channel candidate or the second downlink control channel candidate, the control message scheduling a communication between the base station and the UE over the first component carrier. The UE may then transmit or receive the communication with the base station over the first component carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

Abstract: Wireless communication capabilities are disclosed that support determination of timing advance for a physical uplink control channel (PUCCH) in joint acknowledgement feedback mode of a network having multiple timing advance groups (TAGs) configured per serving cell and multiple control resource set (CORESET) pool index values configured per bandwidth part (BWP). In a first aspect, a method of such capabilities includes receiving a configuration message including at least a feedback mode configuration configuring a joint acknowledgement feedback mode, a TAG configuration for each serving cell, and any CORESET pool indices for the BWPs of the serving cells. A user equipment (UE) receives downlink transmissions and determines a timing advance for a PUCCH with a joint acknowledgement message using the last downlink control information (DCI) message received scheduling the downlink transmissions. Alternatively, a UE may use a predetermined timing advance. Other aspects and features are also claimed and described.
